The Mexico Congressional UAP Hearings, officially titled "Public Hearing on Unidentified Anomalous Phenomena (UAP)", took place in the Mexican Chamber of Deputies on September 12, 2023. This event brought together a diverse group of individuals, including researchers, pilots, military personnel, and government officials, to discuss the phenomenon of UAPs. The hearing gained significant international attention due to the presentation of two alleged "non-human bodies."

  • September 12, 2023: The "Public Hearing on Unidentified Anomalous Phenomena (UAP)" is convened in the Mexican Chamber of Deputies by Deputy Sergio Gutiérrez Luna.
  • September 12, 2023: Jaime Maussan, a well-known Mexican ufologist, presents two cased specimens, claiming they are "non-human bodies" recovered from Cusco, Peru.
  • September 12, 2023: Maussan and others present alleged scientific analyses, including X-rays and DNA results, which they claim support the non-human origin of the specimens.
  • September 12, 2023: Ryan Graves, former U.S. Navy pilot, testifies virtually, reiterating his previous firsthand accounts of UAP sightings.
  • The hearing was officially convened by the Mexican Chamber of Deputies on September 12, 2023, and presided over by Deputy Sergio Gutiérrez Luna.
  • Jaime Maussan presented two physical specimens encased in glass display boxes during the hearing.
  • Ryan Graves, a former U.S. Navy pilot, provided public testimony to the committee via a virtual connection.
  • The National Autonomous University of Mexico (UNAM) has previously conducted carbon-14 dating on samples presented by Maussan, identifying them as approximately 1,000 years old. However, UNAM explicitly stated its work was only carbon dating and did not comment on the origin or nature of the samples.
  • Jaime Maussan stated that the two presented specimens are "non-human beings that are not part of our terrestrial evolution" and were recovered near Nazca, Peru.
  • Maussan claimed that the specimens were found inside diatom (algae) mines and underwent various scientific analyses, including X-rays, 3D reconstructions, and DNA analysis.
  • He further claimed that detailed DNA analysis indicated that "30% of their DNA is unknown."
  • Maussan asserted that the specimens possessed fully formed skeletons, an absence of teeth, light bones, and a cranium with frontal lobes indicative of high intelligence.
  • Witnesses, including military personnel and former pilots, reportedly shared accounts of UAP sightings and encounters.
  • Numerous mainstream scientists and institutions, including the scientific community in Peru, have reportedly challenged Maussan's claims, asserting that the specimens are likely hoaxes or fabricated artifacts.
  • No specific radar or instrument evidence directly related to the alleged "non-human bodies" was presented or verified during the hearing. Emphasis was placed on the physical specimens presented by Maussan.
  • Ryan Graves' testimony, while discussing UAPs, generally refers to visual and occasionally radar data from past incidents, not directly tied to the subject of the alleged non-human finds.
  • Jaime Maussan served as a primary presenter, offering his interpretations and findings regarding the alleged specimens.
  • Ryan Graves, a former U.S. Navy pilot, testified about his experiences witnessing UAPs while in service, emphasizing the need for data collection and transparency regarding such phenomena.
  • Other unnamed witnesses, reportedly including military personnel and researchers, provided testimonies concerning UAP sightings and their potential implications. Details regarding their specific testimonies were broadly summarized in news reports rather than direct transcripts being widely available or scrutinized post-event.
  • The Mexican Chamber of Deputies convened the hearing as an official government proceeding. However, this does not constitute an "investigation" into the presented specimens by a scientific or forensic body. It was a platform for discussion.
  • Peruvian authorities reportedly initiated an investigation into how the specimens might have left the country, citing cultural heritage concerns and potential illicit trafficking. As of late 2023, the actual origin and transport of the specimens remain under scrutiny by Peruvian officials.
  • Maussan presented what he claimed were X-rays and scientific analyses, including DNA reports, from various unnamed laboratories. He highlighted a report, allegedly from UNAM, that determined the specimens were approximately 1,000 years old.
  • UNAM, in an official statement, subsequently clarified that their Institute of Physics performed only carbon-14 dating on samples provided by Maussan in 2017 to determine their age. UNAM explicitly stated that the purpose of their work was not to verify the origin of said samples, and they did not make any claims regarding their non-human nature.
  • Independent scientific experts, including archaeologists and anatomists, who have examined images and presented data, have largely concluded that the specimens are likely sophisticated fabrications, possibly reconfigured mummified remains from various sources.
  • The overwhelming consensus among independent scientists and researchers is that the presented specimens are likely hoaxes or manufactured artifacts, possibly utilizing ancient human or animal remains.
  • Common skeptical explanations include the repurposing of pre-Columbian artifacts, clever taxidermy, or sophisticated fakes designed to appear non-human.
  • The lack of transparency regarding the recovery location, comprehensive chain of custody for the specimens, and the methodology of the claimed scientific analyses has fueled skepticism.
  • Maussan has a long history of presenting alleged alien evidence that has subsequently been debunked.
  • The definitive provenance and detailed composition of the two specimens presented by Jaime Maussan, beyond the carbon dating performed by UNAM, remain officially unexplained with verifiable, independent scientific scrutiny.
  • The exact methods used to create or alter the specimens, assuming they are fabricated, have not been fully elucidated by Maussan or independently confirmed.
  • The full extent of the scientific analyses claimed by Maussan, and their methodology, have not been independently reproduced or verified by the broader scientific community.

The Mexico Congressional UAP Hearings provided a platform for discussion on UAPs and the controversial presentation of alleged "non-human bodies." While the hearing itself was a verifiable government event, the primary evidence (the specimens) remains unsubstantiated by rigorous, independent scientific inquiry and is widely regarded as a probable fabrication by the scientific community.
